Goodwill receives fourth human skull

Police in Austin, Texas, are searching for the person who donated a human skull to a local Goodwill store.

Goodwill volunteers were shocked last month while sifting through donations and discovering the adult skull among boxes of items they see every day. It is not known not when the head arrived, but it is believed it had been there at least a week.

Foul play is not suspected, however; authorities do want to know who donated the skull.

This is the fourth human skull donated to Goodwill this summer. Three were received at a store in Bellvue, Washington, in July.
